My invention relates to chain fasteners, and more particularly to a fastener for 'de- While my invention is hereinafter described as employed more particularly in connection with tire chains, it will be understood that it is useful also in various other relations.

One object of my'invention is to provide a chain fastener, that while it may be readily manipulated to open and close the same, it'is securely held against opening accidentally.

Another object of my invention is to pro-' vide a chain fastener of generally simplified and improved form. i

One'form which my invention may take is shown in the accompanying drawings, where- Fig. 2 is a side elevational view; Fig. 3 is a View similar to Fig. 2, but showing the.fas-' tener in opened position; Fig. 4. shows the manner in which the keeper may be moved to engage or release the'latching lever, and Fig. 5 is' a view taken on the line V -V of Fig. 2. V

The fastener is shown asdetachably con- 7 necting links 6 and 7 which may Joe-the end links of a side chain of a tire chain structure.

The fastener comprisesa connector bar 8, a latch lever 9, and a keeper 10. The connector bar 8 is pivotally oined to the link 6 by a rivet 11, and the latch lever 9'is connected tothe bar 8 by a pivot member 12. The connector bar and the latch lever have semi-circular recesses that serveas a seat for the link 7, as shown more clearly in Fig. 2. The free end of the lever 9 is of hook form, such hook having a nose portion 13 and a heel portion 14 that lie on a line diagonal to the bodyportion of the lever.

The keeper 13 is of yoke-like or flattened loop form as shown moreclearly in Fig. 5. The longer internal diameter of the keeper is of less length than the distance between the keeper,;and the safidrpoints lying on a v line diagonal to the connector bar when'the v the portions 13 and 14 of the hook, so thatit cannot be disengaged from the hook except by a tilting movement from the position shown in dotted lines in Fig. 4, to the full-line posi-f tion thereof. In other words, the distance between the points 13 and 14 of the hook is stomastra s; an casings therefrom; ;simply' by depressing; the i latch ment of the keeperE-wi ll, of course, bring it to operative position, as in-Fig. 2. r Y

said members are inside by'side relation and the'longer internal" diameter of the keeper beingless than the distance between the nose and heel portions of the hook. V V v l 1 A chain fastener comprising a connector bar, a keeper'slidably supported on said bar, a latch. lever pivotally connected at one of its ends to the said bar and having a, back wardly-turned hook portion disposed on lines diagonal to the body portion of the lever, the

dimension of saidjhook portion along said' diagonal lines being greater than the internal diameter of the keeper, and the greatest di-' mension of such hook portion along lines perpendicular to the body portion-of the lever being less than the said internal diameter.
